Abstract
This study observed the frequency with which laboratory rats (Rattus norvegicus) entered polyvinylchloride (PVC) conduits placed in their cages to provide environmental enrichment. The study found that use of PVC conduits by Norway rats varied with subjects' strain, age, sex, and housing condition. Adult male Long-Evans rats rarely entered PVC conduits unless housed in pairs, in which case the lighter (presumably subordinate) pair member frequently used the conduit, possibly to avoid contact with his dominant partner. Adult male Sprague-Dawley rats entered PVC conduits only during the illuminated portion of the day-night cycle and only if housed on shelves exposed to direct overhead illumination. Both juvenile rats and female rats made extensive use of PVC conduits throughout the day-night cycle. This article discusses implications of these findings for determining how best to enrich environments in which laboratory rodents are maintained.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
